Various modifications out departing from the nature or my invention as defined in the claims.

it claim:

1. A speed-indicator for shi= and water currents, compris a. Water-ti; it casing". a shaft journaled therein, a. circint-controlle" located Within said casing, insane for open ating the controller by a rotation of said shaft, an indicator, means for governing said indicator by the controller, a magnetic driving device comprising two rotary members of magnetizahle material arranged in. at tractive relation and each consisting of a plurality of parts extending lengthwise of said shaft, one of said members being locatcd Within the casing and connected with said shaft, While the other member islocated outside the chsing and embraces it, and a de vice for rotating said exterior member.

A spceddndicator for ships and watercurrents, comprising a water-tight casing, a shaft journaled therein, a circuit-controller located within said casing, means for operating the controller by a rotation of said shaft, an indicator, means for governing said indicator by the controller, a magnetic driving device comprising two rotary members of magnetizable material arranged in attractive relation and each consisting of a plurality of parts extending parallel to sai d shaft, one of said members being located Within thev casing and connected with said. shah, while the other member is located outside the casing and embraces the corresponding parts of the inner member, and a. device for rotating said exterior member.

3. 1 speed indicator currents comprising a shaft jourualed therein, an indicator, means .'or governing said indicator by the rotation of said shaft, a magnet c driving device comprising two rotary J'llOHlbCI'S of magnetizable material arranged in attractive re lation and each extending lengthwise of said shaft, one of said members being located Within the casing and connected with said shaft, While the other member is located outside the casing, and a device for ing said exterior member.

4. A speed indicator for ships and Watercurrents comprising a Watertight causing, a shaft journaled therein, an indicator, means for governing said indicator by the rotation of said shaft, a magnetic driving device comprising two rotar 1 members of magncth zable material arranged in attractive rclation and each consisting of a plurality of the said device C may shai't by means 01' for ships and Watcn Water-tight casing, a

l l l n zablc material parts extending lengthwise of said. shaft, of said members being located will casing and connected with said she. the other member is located cu ing and embraces the ca corresponding and a device for rotating her.

5. A speed indicator currents, comprising a casing, a. wa I compartment for ships and water L therein, two shalt jOlliILLniCl within the casing in longitudinal slinemcnt, one oi said shafts projecting to the outside of the casing While the other sh is er.- tirely inclosed within said Watertight compertinent, a device for rotating the shaft which projects to the outside of the-casing, a magnetic driving device comprising two rotary members 01 magnetic material connected with the respective shafts, an indicator, and means for governing 'tid indicator by the rotation of the shaft which is entirely inclosed.

' A speed indicator for ships and water currents comprising a casing, a Watertight compartment therein, two shafts journalcd Within said casing in alinemcnt with cool. other, means located cxteriorly of the casing for rotating one of said shafts While the other shalt is entirely inclosed watertight com partmcnt, a magnetic driving device comprising rotary members oi. magnctizable material secured to the respective sl'iailts, a circuit controller located within the casing, means for operating said controller bythe rotation of the shaft, an indicator and means for governing said indicator by the controller. I

T. A speed indicator for ships and Water currents, coin prising a 'lrame or ca ing having a compartment in losed entirely by stationary Watertight walls, a shaftjournaled in said compartment and located entirely therein, a circiut-coutroller contained in said 'by the controller, another sha t'tyournaled in outside said the casing and located entirely compartment, a device for rotating said sec-- ond shaft, and a magnetic driving device comprising two rotar members of magnetizconnccted with the said shafts respectively.

in testimony whereof l have hereunto signed my name in the presence two subscribing Witnesses.
